What it is
Practical, non-regulated finance help for small businesses: budgets, cash flow forecasts, pricing checks, management reports and business plans for loan or grant applications.
Your first three steps
- Pick a niche, such as trades, hospitality or start-ups, and write a simple one-page service list with prices
- Set up as a sole trader with HMRC and get a quote for professional indemnity and public liability insurance
- Offer a discounted cash flow review to three local businesses and ask for a written testimonial
Who pays
Sole traders, small limited companies, start-ups and community groups that don't have a finance director.
How it makes money
Day or hourly rate, fixed fees for projects such as a forecast or funding pack, or a monthly retainer for regular reviews.
Skills that help
- Strong with numbers and spreadsheets
- Plain-English explaining
- Background in finance, accounting or banking helps
Watch out for
- Advice on investments, pensions, mortgages or insurance is regulated by the FCA, so check what you can and can't say before you start
- Check whether your services mean you need to register for anti-money laundering supervision
- Professional indemnity insurance in case your advice causes a client loss
- Check whether you need to register with the ICO because you handle client data
- Working from home may need permission from a landlord or mortgage lender
